Why does the engine light keep coming on indicating EGR valve in a 2000 Mazda Protege after the EGR valve and the EGR booster sensor were replaced?

Either there is no Voltage or Vacume going 2 the Valve OR the Passagway under the Valve is Blocked.

Clean the EGR Line with carb cleaner to ensure not any blockage.

If you are referring to the check engine light and are still receiving a code indicating EGR valve, then the problem is that the EGR valve is being effected by the problem. The EGR valve is not the problem, it is just the component that is being effected. Code readers only tell you the effected part, not necessarily the bad part. This is one of the big problems with autozone's free diagnostics, you get what you pay for.

I had this issue just a few months ago. Your clutch is going out. I had the flywheel and slave cylinder replaced on my '96 Protege (stick-shift) to fix it.

The answer posted previously seems to be taken verbatim from this site, and probably copyrighted there: Mazda EGR Flow: Low or Excessive? http://www.asashop.org/autoinc/sept2002/techtips.cfm and if that doesn't work, there are additional tips here: P0402 EGR code Help - Automotive Message Forums http://www.automotivehelper.com/topic478910.htm

The Brake Booster is mounted on the firewall and the master cylinder is mounted on the booster. Look at the booster and you will see a very large vacuum line coming from the booster.

Master cylinder is bad and appears to be coming from the booster.

Drivers side, mounted on the firewall, behind the master cylinder. Coming from that booster is a large vacuum line.

I have a 1993 Protege. The hold button keeps the transmission from up shifting. I use it when I am coming down the hill in my neighborhood. Rather than braking the hold button keeps the trans in a lower gear and I remain at a safe neighborhood speed.

These cars had issues with the pedal pressure sensor located in the brake booster. Additionally the brake booster it self is also known for failure on this car.

Perhaps a vacuum leak or bad vacuum check valve in power brake booster
